About US fluid ounces per hour
The US fluid ounce per hour (fl oz/h) equals 3.785411784×10⁻³/128/3600 ≈ 8.215×10⁻⁹ m³/s, used in low-flow medical devices and slow-infusion clinical equipment. A nasal cannula oxygen humidifier delivers humidity at 10-50 fl oz/h of water vapour equivalent; micro-dosing chemical feed pumps for water treatment are calibrated in fl oz/h in US systems. 1 fl oz/h ≈ 8.215×10⁻⁹ m³/s.
About US gallons per minute
The US gallon per minute (gpm) equals 3.785411784×10⁻³/60 ≈ 6.309×10⁻⁵ m³/s, the dominant volumetric flow unit in US plumbing, HVAC, and water-treatment industries. EPA showerhead standards are set at 2.5 gpm; residential water meters size at 3/4"-1" for 5-20 gpm; municipal water-distribution design uses hundreds to thousands of gpm. 1 gpm ≈ 6.309×10⁻⁵ m³/s = 3.785 L/min.
